In the latest glibc, major() and minor() functions are marked as deprecated (glibc commit dbab6577): CC util/libvirt_util_la-vircgroup.lo util/vircgroup.c: In function 'virCgroupGetBlockDevString': util/vircgroup.c:768:5: error: '__major_from_sys_types' is deprecated: In the GNU C Library, `major' is defined by <sys/sysmacros.h>. For historical compatibility, it is currently defined by <sys/types.h> as well, but we plan to remove this soon. To use `major', include <sys/sysmacros.h> directly. If you did not intend to use a system-defined macro `major', you should #undef it after including <sys/types.h>. [-Werror=deprecated-declarations] if (virAsprintf(&ret, "%d:%d ", major(sb.st_rdev), minor(sb.st_rdev)) < 0) ^~ In file included from /usr/include/features.h:397:0, from /usr/include/bits/libc-header-start.h:33, from /usr/include/stdio.h:28, from ../gnulib/lib/stdio.h:43, from util/vircgroup.c:26: /usr/include/sys/sysmacros.h:87:1: note: declared here __SYSMACROS_DEFINE_MAJOR (__SYSMACROS_FST_IMPL_TEMPL) ^ Moreover, in the glibc commit, there's suggestion to keep ordering of including of header files as implemented here. Signed-off-by: Michal Privoznik <mprivozn@redhat.com> --- This still won't solve the build issue completely as AC_HEADER_MAJOR still reports that major() is defined by sys/types.h instead of sys/sysmacros.h. But once they fix it, we are good too.
